GEORGE J. WHITE, OF WASHINGTON, PENNSYLVANIA.

WRENCH.

Specification of Letters Patent.

Patented Feb. 17, 1914.

Original application filed July 8, 1912, Serial No. 708,261. Divided and this application filed October 11, 1912, Serial No. 725,196. Renewed July 17, 1913. Serial No. 779,637.

To all whom it may concern:

Be it known that I, Gnonon J. WHITE, a citizen of the United States, residing at \Vashington, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in renches, of which the following is a specification.

This application is a division of my pending application, Serial No. 7 08,261 filed July 8, 1912 for certain new and useful improvements in wrenches.

The present invention resides in a novel wrench attachment that permits of a pipe threader, die or other device being held whereby it can be easily manipulated, for instance, as threading a pipe.

The invention aims to provide an attachment that can be advantageously used in connection with the wrench disclosed in my pending application.

The invention further aims to accomplish the above results by a mechanical construction to be hereinafter specifically described and them claimed.

Reference will now be had to the drawing, wherein Figure l is a side elevation of a portion of a wrench provided with the attachment, Fig. 2 is a similar view showing the attachment partly broken away and partly in section, Fig. 8 is a plan of the attachment partly broken away and partly in section, Fig. 1 is a cross sectional view of the attachment. and Fig. 5 is an enlarged cross sectional view of the wrench illustrated in Figs. 1 and 2 taken on line V-V Figs. 1 and 2.

Further describing my invention in detail with reference to the accompanying drawing, wherein like numerals denote corresponding parts throughout: 1 denotes a shank having a stationary jaw 2 provided with a transverse opening 3 and a V-shaped seat at.

5 denotes a movable jaw slidably mounted upon the shank and having-a V-shaped seat 6 confronting the seat 1 of the jaw 2.

7 denotes a rack bar carried by the jaw 5 and extending through a nut body 8, carried by the inner end of the shank 1. The nut body 8 is clearly shown in Figs. 1 and 5 and said body has a longitudinal threaded bore 9 to receive the rack bar 7. The bore 9 has a longitudinal groove 10 adapted to provide clearance for the tongue 11 of the rack bar 7. The ends of the nut body 8 are provided with guide grooves for the arms 12 of a yoke 13, said yoke having the sides thereof slotted, as at 141 whereby said yoke can be loosely connected to the nut body 8 by screws 15 or other fastening means. The confronting sides of the yoke 13 and the nut body 8 have oppositely disposed sockets 16 and arranged in said sockets is a coiled compression spring 17 The nut body 8 is held relatively to the rack bar 7 and said rack bar can be rotated to minutely adjust the nut body 8 and the jaw 2 relatively to the jaw 5. By rotating the rack bar 7 until the threaded longitudinal tongue 11 con fronts the groove 10, the yoke 18 can be pressed toward the nut body causing the tongue 11 to enter the groove 10. The nut body can then be rapidly adjusted upon the rack bar 7.

The wrench as above described is simply a type in connection with which my improved attachment can be used. The attachment comprises a handle 18 having a head 19 and this head is provided with a socket 20 to receive the jaw 2 of the wrench. The jaw of the wrench is retained within the socket 20 by a transverse pin 21 located in the opening 3.

22 denotes a holder, hinged or pivotally connected, as at 23 to the side of the head 19 and in this holder can be arranged a die 21, tool or other device. The holder 22 has a lateral flange 25 and hinged to said holder, as at 26 is a gate or die retaining member 27 that has a lateral flange 28 cooperating with the flange 25 of the holder in embracing the jaw 5 of the wrench. The flanges 25 and 28 are connected to the jaw 5 by a bolt 29 and a nut 30.

31 denotes a latch carried by the head 19 for engaging the holder 22 and retaining the same in a closed position.

lVith the handle 18 longitudinally alining with the wrench and with a die or other tool held by the attachment between the jaws of the wrench, it is apparent that the wrench and the attachment can be easily manipulated in connection with a piece of work.

WVhat I claim is 1. In combination a handle adapted to be connected to a jaw of a wrench, a holder supported by said handle, and means carried by said holder and adapted to retain said holder between the aws of said wrench.

:2. In combination a handle bar adapted to be connected to a jaw of a wrench, a die holder pivotally supported by said handle bar and adapted to swing between and be clamped by the jaws of said wrench, and a die retaining member pivotally connected to said die holder.

3. In combination ahandle bar adapted to be connected to a jaw of a wrench, a die holder pivotally supported by said handle bar, a lateral flange carried by said handle, a die retaining member pivotally connected to said holder, a lateral flange carried thereby and cooperating with the first mentioned flange in embracing the sides of the other 15 jaw of said wrench with said die holder positioned between said In testimony whereof I aflix my signature in presence of two witnesses.
